Plasma Activated Organic Fertilizer

December 5th, 2018|

Category: Journal publication Abstract: Improved utilization of organic waste for fertilizer has significant worldwide economic and ecological potential and the use of plasma can help unlock this potential. Organic waste that are used as fertilizer includes animal waste (manure and urine), human sewage, food waste and biogas digestate. Air plasma treatment of aqueous solutions of organic [...]

Improving Organic Fertilizer and Nitrogen Use Efficiency via Air Plasma and Distributed Renewable Energy

December 5th, 2018|

Category: Journal publication Abstract: Synthesis of reactive forms of nitrogen such as ammonia is important in modern agricultural productivity, but present agricultural technology uses reactive nitrogen inefficiently, leading to numerous and growing environmental problems. Animal, human, and food waste all contain significant quantities of organic nitrogen that are transformed into ammonia (NH3) by bacterial degradation of [...]

Modern plasma technology for nitrogen fixation – new opportunities?

November 30th, 2018|

Category: Journal publication Abstract: Norsk Hydro, later Yara, was founded on the Birkeland plasma arc technology for direct nitrogen fixation from air making calcium nitrate. However, from 1908-1920 the Haber-Bosch ammonia synthesis was developed and took over. For more than 100 years, it has been an apparently unrealistic dream to revive and improve the plasma process, [...]
